...method of isolating eka-iodine are Dr. Walter Minder, director of Bern's Radium Institute, and Dr. Alice Leigh-Smith, British student of the late great Mme. Curie. In a burst of international patriotism they named the new element anglohelvetium after their native lands, as Mme. Curie named polonium for her Poland...
...Firestone Tire & Rubber Co.-which branched out into batteries, plastics, steel parts, service stations, cotton mills-announced development of a new automobile spark plug that provides better ignition, quicker starts for cold motors. The plug has electrodes coated with polonium, a radioactive element discovered by the late great Marie Curie (and named for her native Poland). The polonium shoots a steady stream of subatomic particles which ionize (electrify) the air in the spark gap, make it a better conductor when the spark jumps...
Radium E is the seventh and last stage of radium disintegration before it turns into polonium. Its atomic weight is 210. Atomic weight of bismuth is 209. Dr. John Jacob Livingood figured that if he hurled billions of particles of atomic weight i at bismuth, some of them might plow into the nucleus and stick, turning the bismuth into Radium E. Actually, the best particles for his purpose were deuterons whose atomic weight is 2. When the deuterons got close to the bismuth nucleus, they broke into protons and neutrons. The protons recoiled. But the neutrons, of atomic weight...
...leachings, precipitations, crystallizations with apparatus at which a modern physicist would sneer. Much of the time Mme Curie spent stirring a cauldron with an iron rod as thick as one of her thin arms. At last they had a thimbleful of a white salt. In it they found first polonium, finally radium...
...repeated experiment it is known that any electrically charged form of matter will penetrate paraffin, for example, more easily than lead. Bombarding lithium with alpha particles from polonium, the Curies found they were knocking out a ray that penetrates lead more easily than paraffin. By empirical reasoning, the ray produced must be a new kind of ray, since it breaks all known rules. The Curies concluded their ray "cannot be of an electronic or electromagnetic nature." It is probably a ray of neutrons. Irene Curie-Joliot and her husband did much of the preliminary work in radiation that helped Neutron...
